The Dawnbreaker rewards groups that keep the early trash controlled and treat its aerial transitions as mechanics, not downtime.
Opening trash: Ensnaring Shadows is the call: Assign an interrupt to Nightfall Shadowmages' Ensnaring Shadows. The snare/curse is the dangerous cast; use spare stops on lesser casts only after that assignment is covered.
Ship movement: regroup before the next pull: After each flight or platform change, let the tank establish a clean stack point and line of sight before starting the next pack. Ranged pulls from a split group turn simple casts into unrecoverable travel time.
Rasha'nan: plan the transition, not just the burn: Save movement and a personal defensive for the two-phase final boss. The second phase tests controlled skyriding and re-entry; arrive together, then resume damage instead of scattering across the platform.
These are execution priorities, not a fixed pull-count route. Verify weekly tuning, affixes, and your tank's route before the key, then use the source and current videos for difficulty-specific details.
Call dispel and healing-absorb coverage before the cast resolves. Treat the absorb as a group assignment, not an individual healer surprise.
